Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal management systems for compact electronic devices, such as telecommunications equipment, face design constraints that limit the effective dissipation of heat generated by electronic components, necessitating an innovative cooling solution that is both efficient and unobtrusive.
Innovation Solution
A system utilizing a stand with air intake openings distributed around its periphery and a slot that accommodates the device housing, allowing for air convection to draw in cool air, absorb heat from the device, and exhaust heated air through upper openings, effectively promoting natural cooling without altering the device's compact form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional thermal management systems are used in compact electronic devices, then heat dissipation is achieved, but the device design becomes complex and the compact form factor is compromised
Solution Approach 1:
The stand serves as an intermediary thermal management system between the electronic device and the environment. Instead of adding complex ventilation features to the device itself, the stand provides air intake openings and exhaust pathways that facilitate heat dissipation externally, thereby simplifying the device design while maintaining effective cooling
Solution Approach 2:
The invention moves the thermal management function from the device housing dimension to the stand dimension. By positioning air intake and exhaust features in the stand rather than in the device housing, the solution adds a spatial dimension to heat dissipation, allowing the device to maintain its compact form factor while achieving effective cooling
2Temperature
If additional ventilation features are added to the device housing, then heat dissipation improves, but the sleek compact design is compromised
Solution Approach 1:
The ventilation and thermal management features are extracted from the device housing and relocated to the stand. This separation allows the device to maintain its sleek, compact design without vents or complex airflow features, while the stand independently handles all thermal management functions through its own air intake and exhaust openings
3Temperature
If the device is positioned to maximize heat dissipation, then cooling efficiency improves, but the unobtrusive placement option is lost
Solution Approach 1:
The stand is designed with air intake openings distributed around its periphery and natural convection pathways that automatically facilitate heat dissipation regardless of the device's rotational orientation. The thermal management system serves itself through natural airflow patterns, eliminating the need for specific device positioning while maintaining cooling efficiency and allowing flexible, unobtrusive placement
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides stable and efficient heat dissipation for compact electronic devices, enhancing their operational reliability by leveraging natural convection to remove heat without the need for additional ventilation features on the device itself, thus maintaining a sleek design while ensuring effective thermal management.
Implementation Method 1
Convection causes air to be drawn into the stand through the stand air intake openings and communicated from the interior of the stand into the device air intake openings
Implementation Method 2
Heat in the device housing is transferred to the air as the air passes through the device housing, and the heated air exits the device housing through the device air exhaust openings, thus removing heat from the device housing

AI summary
A convection-cooled electronic system includes an electronic device and a stand. The electronic device has air intake openings in a lower housing portion and air exhaust openings in an upper housing portion. The stand has air intake openings. The stand has a periphery, a flat base, and a slot extending across the widest portion of the stand. The slot has a shape configured to receive the lower portion of the device housing. Heat emitted by electronic components within the device housing creates airflow by convection, which causes air to be drawn into the stand through the stand air intake openings and communicated into the device air intake openings. The air is heated as it passes through the device housing, and the heated air exits the device housing through the air exhaust openings.
